The St. Vincent Parrot, also known as Amazona guildingii, is a beautiful bird species endemic to the island of St. Vincent in the Caribbean. This parrot has captured the fascination of many people due to its vibrant colors, unique traits, and endearing personality.

In this article, we will delve into how to identify this species, its different plumages, and the basics of its life cycle.


One notable characteristic of the St. Vincent Parrot is its size. This species is relatively large, with a length of approximately 40 centimeters and a weight of around 480 grams.

It has a massive beak, which is colored orange or red, and the head and neck are covered in green feathers with a bluish tinge. Its wings have bright green plumage with blue and yellow edges, while the tail is comprised of green feathers with a red base.

Finally, its eyes are brown, and the feet are grey. Field


Locating this species in the field may seem daunting, but some factors may assist birdwatchers.

This parrot can be spotted in the canopy of humid and montane forests within the mountainous terrain of St. Vincent. If you are unsure about its presence, listen for its boisterous and raucous squawks.

You may also see it flying in pairs or small groups, especially during the morning or late afternoon.

Similar Species

It is crucial to differentiate the St. Vincent Parrot from its other Amazon parrot relatives. An easy mistake to make is confusing this species with the Imperial Amazon Parrot.

The Imperial Amazon has a green head and a thick red stripe across its forehead, while the St. Vincent Parrot has a bluish tinge in the head and neck areas. The Yellow-fronted Amazon can also be mistaken for the St. Vincent Parrot, but the former has a yellow patch on its forehead.


This species has different stages of plumage throughout its life cycle. The juvenile plumage differs from the adult ones, and breeding plumage is distinguishable from non-breeding.

Juvenile Plumage

After hatching, the chicks have an entirely different plumage compared to adults. They have duller greenish-grey plumage with a brownish tinge in their feathers.

Adult Plumage

St. Vincent Parrots generally have two main plumagesthe non-breeding and breeding plumages. During the non-breeding period, the feathers are worn out, and the colors are duller than the breeding season.

The colors are blackish-grey on the beak, black on the forehead, and brown on the eyes. The neck is green, and the wings have blue and green feathers without the yellow margins.

On the other hand, the breeding plumage presents a significant transformation. The feathers become sharper and brighter, and a thick red line, which previously delimited the green and blue feathers on the wings, disappears in favor of a yellow one.

The head and neck have a brighter blue tinge visible even from a distance.


St. Vincent Parrots undergo molting, where they shed their old feathers to give way to new ones. The process of molting can take up to a year to complete.

Juveniles molt around eight months of age, with the process gradually taking up to nine months. In conclusion, the St. Vincent Parrot is an exciting bird species that one must appreciate.

As a part of the conservation effort of their valuable and unique ecosystems, efforts are made to protect this species worldwide. With the knowledge of identifying the St. Vincent Parrot, understanding their different plumage variations, and recognizing their molting process, everyone can learn how to observe and appreciate this fascinating species.

The systematics history of a species describes how taxonomists have organized and classified it over time. Systematics history is particularly crucial in understanding the evolution, distribution, and relatedness of species.

In this article, we will discuss the systematics history of the St. Vincent Parrot, covering topics such as geographic variation, subspecies, related species, and historical changes to distribution.

Geographic Variation

The St. Vincent Parrot is endemic to the island of St. Vincent in the southeastern Caribbean. This island is 18 by 29 kilometers in size and has a rugged, mountainous terrain covered primarily by tropical and montane forests.

It is within this forested habitat that the St. Vincent Parrot thrives. Over time, St. Vincent Parrot populations have developed distinct differences, mostly as a result of isolation from one another.

Indeed, while the species thrives on St. Vincent, populations in wild isolated populations on the slopes of the Soufrire volcano may differ from the parrots that inhabit alternative areas of the island. Other small changes to the traits and morphologies of St. Vincent Parrots have occurred over time due to factors such as diet, environmental pressure, and mate selection.


Taxonomists assign subspecies to animals that share certain characteristics that make them distinct from other specimens of the same species. Although there is some disagreement among scientists on St. Vincent Parrot subspecies, taxonomists have identified two subspecies so far.

The first subspecies is Amazona guildingii guildingii, which is endemic to St. Vincent. This subspecies has deep green feathers with an occasional blue tint, a yellow beak, and a red patch on the wing.

This subspecies is sometimes informally referred to as the St. Vincent Amazon. The second subspecies of the St. Vincent Parrot is A.

guildingii hesterna. This subspecies was once distributed throughout the Grenadine Islands of the eastern Caribbean.

It is smaller and has darker plumage than its St. Vincent counterpart. However, translocation, habitat degradation, and overhunting have reduced this subspecies to a few breeding pairs.

Related Species

Amazona guildingii is a part of a clade of Amazon parrots known as the “Greater Antillean Parrots” that originated in South America. The Greater Antillean Parrots were distributed in several waves over the Lesser Antilles and the Caribbean and have diversified into several groups.

Some scientists have proposed that A. guildingii and another parrot species, A.

arausiaca of Dominica, form a closely related hybridization group.

Historical Changes to Distribution

The historical distribution of the St. Vincent Parrot has undergone several changes. Even before the arrival of humans, the volcanic origin of the island led to frequent landslides or volcanic eruptions that created new habitats of varying qualities, leading to fluctuations of the parrot population.

Abundant trade winds may have played a role in dispersing or colonizing new lands, leading to the emergence of new populations.

With the arrival of humans, the distribution of the St. Vincent Parrot declined significantly due to deforestation, habitat destruction, and overhunting.

In the past, the parrots have been killed as pests, and during periods of food shortage, they were hunted for food. The combination of these factors pushed the species towards extinction.

At some point, the St. Vincent Parrot was abudnant and was even exported live to Europe for display purposes. However, by the 1970s, the population of the St. Vincent Parrot was reduced to under 500 birds, leading to its classification as an endangered species.

Conservation efforts have worked to mitigate the negative effects of past habitat destruction and overhunting. The species’ population has been gradually stabilizing, although vigilance remains necessary to prevent renewed threats to the population.

Living in nature preserves, St. Vincent Parrots are actively protected, and an increase in enforcement of anti-poaching laws may help to prevent the illegal trade of this and other parrot species. In summary, the conservation status and distribution of the St. Vincent Parrot are tightly related to the historical and present anthropogenic influences.

Evidence suggests that the parrot population has evolved in part due to ecological situations and has settled into subspecies with distinct morphologies. Understanding the systematics history of the St. Vincent Parrot is valuable to naturalists interested in understanding the species’ evolution, diversity, and relatedness.

The St. Vincent Parrot is an exotic bird species native to the island of St. Vincent in the Caribbean. The species thrives in the dense, humid tropical and montane forests that cover much of the island.

In this article, we will discuss the St. Vincent Parrot’s habitat, movements, and migration.


The St. Vincent Parrot thrives in its natural habitat, consisting of the lush, dense tropical and montane forests of St. Vincent. These forests occur at elevations between 200 and 1000 meters above sea level and provide critical resources such as food and shelter for the parrots.

In particular, those habitats located in the volcanic talus slopes of La Soufriere and other steep mountain peaks offer great protection for St. Vincent Parrots. These birds have adapted to their forest environment, exploiting resources that occur in the tree canopy or the forest understory, unattainable to other bird species.

Indeed, their sharp claws and powerful beaks enable them to climb and break through wood to consume fruits, seeds, flowers, and leaves, while suitable nest cavities protect their young from predation or other dangers. Additionally, the vegetation present in the forests provides several essential shelter and protection mechanisms for the St. Vincent Parrot, staying hidden from predators.

Movements and Migration

The St. Vincent Parrot is known to be a relatively sedentary bird species, with most birds remaining in their natural habitat throughout the course of the year. However, these birds have been known to make short-distance movements within the island, particularly in relation to food availability or the need to find suitable nesting sites.

One reason for the lack of movement of St. Vincent Parrots may be because they do not migrate long distances. Given that this species is endemic to the island of St. Vincent, there is, in fact, no need for migratory behavior.

However, older chicks and juvenile birds may disperse to new areas once they have grown up and developed into fully-functional adults. Despite being relatively sedentary, various environmental variables such as food availability, changing climate, or other ecological conditions may lead to changes in St. Vincent Parrot behaviors.

By tracking these birds using GPS and telemetry devices, scientists have found that these birds can cover significant distances, albeit short-lived. Such advancements in technology have been used to track non-breeding St. Vincent Parrots, improving the understanding of their behavior.

The availability of vegetation and food sources, particularly fruits and seeds, is one of the leading factors that influence the movement of St. Vincent Parrots. Their diet is primarily fresh fruit, seeds, flowers, and leaves from native and non-native tree species.

During breeding seasons, St. Vincent Parrots tend to stick around their nesting sites as the adults and young chicks require constant feeding for their growth. The St. Vincent Parrot has a lifespan of almost 17-20 years in the wild, and during this time, they can move between different forested areas and explore the wider range of resources found on the island.

Population studies have revealed that St. Vincent Parrot populations tend to concentrate on the western side of the island, with larger divergences rarely being witnessed in the past decades.

Conservation Efforts

St. Vincent Parrots are a protected and endangered species. In the past, the native forests of St. Vincent suffered from severe habitat destruction, primarily due to direct human activities such as deforestation, habitat modification, overhunting, and forest fragmentation.

Some forests were cleared for agricultural purposes, logging, and other purposes, leaving only small patches of native vegetation for the St. Vincent Parrot. The result is a decline in the population of the St. Vincent Parrot and several other associated species leading to a decrease in habitat availability for this bird.

To protect the St. Vincent Parrot, several conservation programs have been initiated, especially within the last decade. Management plans have been implemented to protect and restore the parrot’s natural habitat, ensure their safety and minimize human impact on the population.

These include habitat protection, the creation of new native forests on the island, enforcement of strict anti-poaching laws, and collaboration with local people to support the sustainable use of forests and natural resources.

In conclusion, the St. Vincent Parrot is an extraordinary bird species that inhabits its natural habitat of dense tropical and montane forests of St. Vincent.

Despite being relatively sedentary, various environmental variables, such as the availability of food and vegetation, may cause changes in behavior. Through the implementation of effective conservation efforts, we can help protect this precious species by preserving its intact ecosystem and other critical habitats.

The conservation of the St. Vincent Parrot not only benefits this species but also helps to support the wider range of ecological values of the forests and provides a habitat for other associated species.
